Appiication filed January 25, 191'?. serial 110,144,405.

To all whom t may concern:

,',Be it known that I, FRANK J. .Bisonor, la citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new -and Improved Curtain-Pole, of which the following Vis a full, clear, and exact description.V

My invention has for its object toprovide a pole having curtain-supporting .means which permitthe ready adjustment of the curtain relatively to the` pole. The curtain supporting means consistsof hangers which extend through a slot lin a guide, the hangers within the guide having each an opening in which a bearing ball is disposed, the bearing ball engaging the inner side of the guide. The guide is disposed inra casing having a slot through which the hangers extend, an operating cord which extends in the casing being adjustably secured tocertain of the hangers. f

Additional objects of the invention will appearY in the following specification, in which the preferred form-ofthe invention is disclosed. 1 Y. j j e In the drawings similar reference characters denote similar .parts in all the views, in which- Y l Figure 1 is alongitudinal sectional view of mycurtain pole; j

Fig. 2 is yan enlarged sectional view similar to that shown in Fig. 1; i

. Fig.l 3 is a sectional plan view of the curtain pole; j

Fig. 4 is anenlarged sectional view on the line4-4ofFig.2; e

Fig. 5 is an enlarged sectional view on the line 5 5 of Fig. 2;

Fig. 6 is anenlarged line 6-"6 ofvFig. 2;l j

.Fig 7 is an enlarged sectional view on the line 7-7 of Fig. 2;"and

Figs. 8 and 9 are enlarged sectional views illustrating the means for securing thehangers to the operating cord. e v

Bv referring to the drawings, it will be seen that a guide .10, is provided, this guide 1() having a groove 11 in its top and a slot 12 in its bottom.l Securedl to the guide 10 andspaced apart there are disks13 which engage the innerfsides of a casing 14 in which theguide 10 is disposed. This casing 14 ,has a slot 15vat its bottom. The disks 13 are cutaway at 16 from the slot 12 in the guide 10, vto the slot 15 in' the, easing 14.

sectional. view on the There are inner flanges 17 at the sides of the slot 15 .for engagingV the lower portions of the disks 13 to prevent the rotary movement of the disks with the guide 1() relatively to the casing 14. i

Extending upwardly through the slots 15 and 12 there are hangers'18, the said hangers 18 having ring portions 19 disposed in the guide 10, a bea-ring ball 20 being disposed in each of the ring portions 19, these bearing balls 2O being suilicientlv wide to prevent their movement through the slot 12, so that. the bearing balls 20 will prevent the downward movement of the hangers 18 and will also assist in the ready `movement of the hangers 18 along the casing 14 when such movement is desired.

Two of the adjacent hangers 18 are provided with means by Vwhich they may be secured to the operating cord 21. As will be seen by referring to Figs. 1, 2 and 3 of the drawings, these last mentioned hangers are preferably disposed next to each other, and are indicated at 18a. Each of the hangers 18a has a member 22 with two guide ways 23 and a threaded orifice 24, each hanger 18EL also having a second member 25 with two guide members 26 and guideways 27, 27a and 27b in which a screw 28 is disposed, the threadof this screw meshing in the threaded orifice 24 so that the screw 28 may be turned to press the screw head 28a against the lower portion of the member 25 and thereby move the clamp member 29 on the member 25 in the direction of the clamp member 30 on the member 22, the said clamp members 29 and 30 clamping the operating cord 21. Inasmuch as the heads 28a of the screws 28 extend below the slot 15 it will be understood that the screws 28 may be actuated to free the hangers 18al from the operating cord 21 to permit of the adjustment ofthe hangers18a. relatively to the operating cord 21. After adjustment the hangers 18al may be again secured to the operating cord by means of the clamping members 29 and 30 and the screw 28. rIhe bottom of each of the hangers 18 and 18aL are fashioned into a ring 31 for engagement by the curtain pins 33 which are secured to a curtain 34 in the customary manner.

Disposed around the lower portion of the end 31 of theguide 10 there is a U-shaped member 35, and disposed around the'lower portion of the end 36V of the guide 10 there is another U-shaped member 35, the sides of the lower portions'oi1 these U-shaped memi bers beingupwardly at' 37A against the outer sides of the guide 10 to prevent the guide ltrom spreading apart and thereby abnormally opening the slot 15. Below the U- shaped member 35. attheend 31 of the .guide 10 there is a pulley 38 disposed on a vertical aXis the pulley 38 beingY spacedfromthe U- shaped member 35 by a block 39. lThe operating cord 21 is disposedaround the pulley f38andis held in'place by a keeper 40"\vhich thesblock 44and vthebracketl 43 being held injp'laee 4relatively.t'o the guide 10 by'a bolt The operating cord 21 at one side ofthe pulley 38 is `secured tofoneof'thehangers 18a and at the otherv's'ide of the pulley 38 the pei'atingcord 21'.is secured to the other hanger 182i. The two ends ofthe 'operating cord2`1 aretheirdisposed one over each of the pulleys'46 Vwhich are journaled von a horizontal axis to the-bracket 43, .the ends ILO-ofthe operating 'cord' 21 passing down through an opening47 lat the bottomof the ea`sin'gj14.V By pulling one ofthe .ends 48 o' the `operating lcord? 21, the hangers 18a will be ymovedfawayiroin'each other and in the direction ofi the ends of thejcasing 14, and by engagemei'ito 'the han-gers 18*l with thehangers 18 the hangeis18between the hangerslSzand the ends of theuca'sing` will be'nioved with the yhangers 18`inthe direction of the,`V ends. oitfthel casing.- VVh'en the otherv end 48 ofthe operatingcordi 21 is pulled downwardly it'will move th'e hangers '18? in the ldirectionoi' each other, and the hangers 18` will draw the curtain,- which:y will pti-ill the hangers 18to the desired supporting nosiftonswHavingthns describedmy' invention, I claim as new, and 'desire to secure by Let-ters Patent: ..1 l
